Thermodynamic Bounds from Otto--Villani Functional Inequalities
Abstract
The dissipation in the relaxation of an ensemble of conservative stochastic systems towards the steady state is quantified by the free energy difference. Functional inequalities within the framework of [F. Otto and C. Villani, J. Funct. Anal. 173, 361 (2000)] are here revisited which connect the free energy dynamics and optimal transport, offering a geometric perspective on the instantaneous speed of relaxation in the presence of potential barriers. These are illustrated with numerical relaxation experiments on Landau-Ginzburg potentials.
